Handbook for the GREAT08 Challenge: An image analysis competition for cosmological lensing
Sarah Bridle, John Shawe-Taylor, Adam Amara +35
The GRavitational lEnsing Accuracy Testing 2008 (GREAT08) Challenge focuses on a problem that is of crucial importance for future observations in cosmology. The shapes of distant g…
COSMOS: 3D weak lensing and the growth of structure
Richard Massey, Jason Rhodes, Alexie Leauthaud +17
We present a three dimensional cosmic shear analysis of the Hubble Space Telescope COSMOS survey, the largest ever optical imaging program performed in space. We have measured the…
The Shear TEsting Programme 2: Factors affecting high precision weak lensing analyses
Richard Massey, Catherine Heymans, Joel Berge +28
The Shear TEsting Programme (STEP) is a collaborative project to improve the accuracy and reliability of weak lensing measurement, in preparation for the next generation of wide-fi…
Weak gravitational shear and flexion with polar shapelets
Richard Massey, Barnaby Rowe, Alexandre Refregier +2
We derive expressions, in terms of "polar shapelets", for the image distortion operations associated with weak gravitational lensing. Shear causes galaxy shapes to become elongated…
The Shear TEsting Programme 1: Weak lensing analysis of simulated ground-based observations
Catherine Heymans, Ludovic Van Waerbeke, David Bacon +22
The Shear TEsting Programme, STEP, is a collaborative project to improve the accuracy and reliability of all weak lensing measurements in preparation for the next generation of wid…
